Description

Solid-state chemicals often reside on screens or mesh-like devices through which water jets pass. However, the screens of most cleaning systems are either mounted on the cleaning system unit or integrally molded . Over time, the screen may become partially or completely clogged, significantly reducing the effectiveness of the overall cleaning system. In such cases, the user needs to remove the chemical product from the screen, which may give them an opportunity to interact with the harmful person. Similarly, if a solid chemical product is not completely dissolved and the user wants to replace the solid chemical product (eg, with a new type or new chemical formula solid chemical product), the user can manually remove the remaining chemical blocks. , And / or a new chemical block must be placed on top of the old chemical block. The former provides yet another opportunity to interact with harmful people. The latter can reduce the efficiency of the system due to heterogeneous dissolution and result in undesired mixing of chemical cleaning agents.

16-21 show that an additional aspect of the lower member or portion 40 is not an inclined shape, but instead incorporates or is integrally molded with the screen portion 200. The lower member 40 integrally molded with the screen 200 may be attached to the upper portion or member 30 as previously disclosed. For example, as well shown in FIGS. 20 and 21, the lower member 40 may include an internal screen surface 202. An annular rim 204 extends from it. The rim 204 may extend to the outer edge of the screen 200 or may be radially separated from it before extending generally apart. An annular outer rib 205 may be present on the outer surface 203 of the screen 200 as described below. Inside the rim 204, the lower member 40 may include a mounting portion 206 for mounting on a portion of the upper member 30. For example, the interior of the rim 204 may include a threaded surface to interact with the threaded surface of the upper member 30. Further, as shown in FIG. 21, the inside of the rim 204 may also include an annular notch 207 and may be snap-fitted onto the upper member 30. Furthermore, the rim 204 of the lower member 40 may be at least partially larger than the region of the upper member 30 so as to provide frictional fitting between the members 30, 40. Other methods of joining both members 30, 40 such that the product is encapsulated or stored therein are understood and are considered part of the present disclosure. In addition, the rim 204 may include a sealing ring 208 formed therein or above to help seal both members together.

By integrally molding the screen with the lower member 40, a number of advantages are provided. For example, as will be understood, the configuration of the holes with the screen, including but not limited to size, shape, number, angle, etc., can affect the amount of fluid passing through in contact with the product stored inside. Therefore, choosing a screen configuration can help provide a more constant solution based on the amount of product in contact with the fluid. By integrally molding the screen with the lower member 40, the type of product to be dissolved / mixed by the solution, the desired concentration level, the change in fluid (temperature, flow velocity, etc.), the change in indoor climate (temperature, humidity, amount of light, etc.) ), And, based on conditions including, but not limited to, other external factors that may affect the resulting concentration, the flexibility to change the composition is increased. Therefore, different covers with different screen configurations can be replaced as needed. In addition, if the product is used in a known location, a known climate, or a known solvent, the screen may be selected during product containment. It is not necessary to replace the entire device 12, instead different members 40 with different screens can be replaced.

Example 1
Approximately 4000 grams of product was contacted with fluid passing through a lower member with integrally molded screens of various configurations. Screen sizes include: (1) holes of approximately 1/4 inch opening size with 0.15 inch ribs (2) holes of approximately 1/4 inch opening size with 0.08 inch ribs. And (3) include 1/2 inch screen holes with 0.15 inch ribs. The fourth experiment was done without any screen. Numerous dispensings were performed to bring the product into contact with a certain amount of fluid to determine the number of dispensings required to erode about 4000 grams of product. Dispensing included 1 second every 90 seconds. In the absence of the screen, the product was eroded in about 550 dispensings. The 1/2 inch screen and 0.15 inch ribs eroded the product in about 650 dispenses. A 1/4 inch screen with 0.15 inch ribs eroded the product in about 750 dispenses. Finally, a quarter-inch screen with 0.08-inch ribs eroded a product that weighed just under 4000 grams in about 1050 batches.

Furthermore, changes in the screen, including the size and shape of the holes, and changes in the distance between the screen and the fluid / liquid source can be utilized with any of the concepts illustrated and / or described herein. I want to be understood. For example, if the screen is integrally molded with one of the first or second parts of the device, or if it is simply positioned within the device as a separate member, the ability to change the composition of the screen will dissolve the fluid. It is not important to provide the flexibility and variability to determine the desired contact between the and the product stored in it.
